Hostels Amsterdam Festival & Events

For 3 days Amsterdam’s Leidseplein, Museumplein, Nieuwmarkt and Waterlooplein will be one big cultural stage. There will be hundreds of free concerts, theatre and comedy shows and other performances to visit as a way to celebrate the start of a new cultural season!
All shows and performances are for free, but make sure you arrive at the shows in time, since there might be a bit of a queue. http://www.whatsonwhen.com/events/event.asp?/events/~26733.jml
